IMPROVEMENT IN FUNNEL-FILTERS.

Specification forming part of Letters Patent No. 180,368, dated July 25, 1876; application filed vMarch 4, 1876.

To all whom it may concern Be it known that we, DANlEL D. PAUL and JOHN G. RAMER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania,

I have invented certain new and useful Improvements in Funnel-Filters; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference heilig' had to the accompanying drawing, which forms part of this specification, and which is a broken perspective of a funnel with my improved lter applied.

The object of our invention is to provide a funnel-ilter of cheap and simple construction,

' which can be readily inserted and withdrawn,

applied. B represents a disk of wire-gauze, the outer edge of which should be bound or seamed, to prevent breaking or rupture. C shows a central metallic washer, through which passes a bent spring-rod, D. The upper part of this rod forms a loop, d, which serves as a handle. The two lower ends d d of the rod D are curved outwardly, so as to impinge against the neck ofthe funnel, thereby keeping the filter in place. The extremities ofthe rods d d terminate abruptly, forming sharp corners, so. as to adhere to the sides Aof the funnel-neck, and preventing the accidental movement of the filter Within said funnel.

What we claim as our invention is- As a new article of manufacture, the funnel-filter herein described, consisting vof the wire-gauze disk B, central washer C, and rod D, bent to form the handle d, and tlaring legs d d', constructed and arranged for operation, substantially as shown and described.

ln testimony that we claim the foregoing we have hereunto set our hands this 25th day or' February, 1876.
